Application filed Mlmh19,1906. Serial No. 306.802.

' ville, in the county of Renville and State of- Minnesota, have invented certain new and useful Improvements in Vehicle-Couplings;

chine or other vehicle.

and I do declare the following to'be afull, clear, and exact description of the invention,

such as will enable others skilled in the art to, D

tral position that the point 16 of the hook is which it appertains to make and use the same, reference'being had to the accompanying drawings, and tothe figures of reference marked thereon, which form a part of this specification. I

My invention relates to nnprovements 1n vehicle-couplings; and the, object is to rovide a cheap but efiicient means for coup ing together any two vehicles, but especiallyfor coupling readily the pole ofa portable threshing-machine to a traction-engine This ob ject I attain by the novel construction and combination of parts illustrated in the accompanyingdrawings, in which Figure 1. is a top or'plan view of my im proved couplin as applied between a traction-engine an a pole of a threshing-ma- I Fig. 2 is a longitudinal vertical substantially central sectional view of the coupling shown with the pole in place, but not intersected. 3

Referring to the drawings by reference-numerals, 3 designates the body or shell of the GOlPliIlg. It" is formed of a thin bottom i an flarlng lips 5, 6, 7, and 8, of which 8 is the upper one and consists of a flat transyerse bar inclined downwardly with its rear edge. y

-- Extending rearwardly from said lips are the side ribs 9, which, with their rear ends,

unite into a loo or box 10, throughthe rear, wall 11 of whic there is a hole for a bolt 12, extending from the dead-wood 13 or any other suitable part of the traction-engine,

while the fiat tailpiece14 bears in under the timber and the nut 15- on the bolt holds the coupling detachably to the engine. The side ribs are near the middle brought together to form cheeks between which the couplinghook 16 is pivoted on the bolt 17. Said hook is constantly pressed downward by a s ring 18 und'er its near rear arm or tail '19.

en it is to be raised, the o erator' on the;

engine pulls the, hook upwar by the chain 20 and ring 21, which is within "convenient. reach upon the engineother vehic e to be coupled to the engine.

, 22'is the, ole of the threshing-machine or The hole is beyond itsv front end provided with a horizontal forwardly-elevated ring or eye 23, having arms 24 secured upon the sides of the pole. v

In the. act of coupling, the eye or 100 23 is simply held in a'position to strike the nnel or mouth of the shell, and as the engine is reversed the, shell receives the loop and by its converging sides 9" guides it to such a cenbound toengage it, and as the loop is curved upward at the front end and rests on the bottom of the shell at the point 25 thehook gets a very good hold, so it cannot possibly become disengaged accidentally.

While the coupling may be forged and put together in various ways, I prefer to cast from malleable iron or similar material the entire shell, with its bottom-4, side ribs ,9, rear rib 11, and mouth 5 6" 7 8, all in one piece. Also the dog or hook 16 and the loop 23 24 are each made integral of suitable material.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. In a coupling of the class described, the combination with anelongated shell securable to a traction-engine and com rising a flaring mouth, a bottom and vertica side and rear rlbs formed integral, said side ribs convergin from the mouth of the shellto near the mi dle of it, a downwardly-'spring-pressed coupling-hook pivoted between said side ribs, and a horizontall 'sposed eye or loop securable to the en of a pole and adapted to be guided into engagement with the couplin hook by the converging side ribs of the she said eye or loop bemgwith its front end inclined upwardly'from the bottom of the shell for the purpose set forth.

2. In acoupling of the class desc'ribed, the combinationwith a shell having at one end a flaring mouth and converging sides extending rearwardly therefrom, and at the other end a vertical perforated rib adapted to be bolted to atraction-en ine and in the rear of saidrib a horizontal ri and a downwardlyspring-pressed coupling-hook pivoted in the ICC ell and adapted to engage an eye on the end of a pole of a vehicle;

3. In a coupling of the class, described, the

combination with an elongeted shell secur-' able to atraction-engine and comprising a flaring mouth, a bottom, vertical side and rear I'lbS formed integral, said side ribs-con-.

verging from the mouth of the shell to near the middle of it, a downwardly springbe disengaged from the eye.
